  • Patent number: 10994071
    Abstract: An adapter for use with a syringe and a power injector includes an outer ring having a first end configured for passage of an end of a syringe having at least one flange. An inner ring is disposed coaxially within the outer ring. The inner ring has a first end including at least one flange slot. A magnet fixed relative to the inner ring such that when the syringe end is disposed in the outer ring and the at least one flange engages the at least one flange slot, rotation of the syringe causes rotation of the inner ring and magnet relative to the outer ring.
    Type: Grant

  • Patent number: 8038123
    Abstract: A fluid handling device, such as a needlefree access device, includes a housing having an inlet and an inlet channel; and a flow control member comprising a combination outlet, biasing and piston member. The flow control member includes a piston section moveable between a closed position in which the piston section is in the inlet channel and an open position in which the piston section is inside the housing below the inlet channel but allows fluid to flow through the inlet channel; a biasing section connected to the piston section that normally biases the piston section into the inlet channel; and an outlet section connected to the biasing section having an outlet fitting in fluid communication with the inside of the housing. The piston section, biasing section and outlet section are connected together such that they can be handled as one piece when assembled with the housing to make the needlefree access device.
